Why TerrariaModder

A different way to mod Terraria

Harmony runtime patches. No modified game files, no recompilation, no separate executable.

⚡

Works on Terraria 1.4.5 Today

Runs on the latest vanilla Terraria without waiting for a port. Just install and go.

🔧

Runtime Patching via Harmony

Patches the game at runtime — no modified game files, no binary replacements, fully reversible.

🤝

Works Alongside tModLoader

Both can be installed at the same time. TerrariaModder runs on vanilla Terraria; tModLoader runs on its own separate install.
